There is a percent formula for all of these types of percent problems.
It is : is/of = %/100
224 is what % of 640
is = 224
of = 640
% = x
now just sub
224/640 = x/100
cross multiply because this is a proportion
(640)(x) = (224)(100)
640x = 22400
x = 22400/640
x = 35......so 224 is 35% of 640
Answer:
A. 4
Step-by-step explanation:
First rearrange the temperatures from low to high
60, 65, 68, 69, 69, 70, 70, 70, 71, 71, 73, 74, 75, 77
There are 14 data,
Q1 = 4th data = 69
Q3 = 11th data = 73
Interquartile range = Q3 - Q1 = 73 - 69 = 4
I hope this helps you
2 (B+4)=3
B+4=3/2
B=3/2-4
B=-5/2
The Exact Form : 1/2
Decimal Form : 0.5
∠ACB is an inscribed angle, so
m∠ACB= (1/2)mAB =(1/2)*50=25⁰
m∠ACB= 25⁰
